Letters Patent No. 95,418, dated October 5, 1869.

IMPROVEMENT IN MACHINES FOR SOLDERING TIN' CANS.

The Schedule referred to in these Letters Patent and making part of 'die same.

To all whom it may concern:

-Be it known that 1, JOHN G. BORDEN, of Brewster Station, in the county of Putnam, and State of NewYork, have invented a new and improved Soldering-Machine; and Ido hereby declare that the fcllowing is a full, clear, and exact description thereof, which will enable those skilled in the art to make and usethe same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to new and useful limprovements yin a machine for soldering tin 'cans and other articles of tinware, and consists in soldering the joint by revolving the corner of the can or other articlein a reservoir of meltedsolde'r, in contact. with a soldering-iron, and with solder on the inside of the cans or other article, which solder is melted by the heat imparted by the .soldering-iron, the result being the meeting of the melted solder I(in the joint) from both 'the 'inside' 'and outside, thus insuring a perfect' joint, the arrangement and operation being as hereinafter more' fully described.

In the accompanying .plate of drawings- Figure 1 represents a sectional side elevation of the machine, the section being through the-'line a: :1: of fig. 2.

Figure 2 is a top or plan view.

. Similar letters of reference indicate corresponding parts.

A is the. stove, in the top of which is the reservoir B, in which the solder is melted.

C is the soldering-imm which is made of copper, or of any other suitable metal.

This iron is attached to the rod D, which extends back, and is secured to the frame E, as seen in theV drawing.

There is a cavity in the solder-reservoir B, which receives the iron C, and the iron rests on pivots, on

the bottom of the reservoir, as seen in iig. 2, so that the ironacts asa lever, whose fulcra are the pivots, and the resistance the rod D, which springs when a weight or pressure is applied to the long end at f.

For general work the iron C is suflicient, but if desirable for heavy work, side irons, similarly arranged or working laterally, are to be employed.

G represents a tin can, which, in soldering, is grasped by the fingers of the bent levers H.

I is a shaft, supported inau inclined position by thel frame E, in suitable boxes. l

This shaft revolves, and is also given a longitudinal motion by means of foot-treadle J, which is connected with the outer end of the shaft by the cord K, as seen in tig. 2.

This cord passes over a pulley, L, on theframe, so-

that a downward motion of the treadle forces the shaft downward toward the stove.

The lower end of the shaft is tubular, and on its extreme end there is a collar, m, provided with forked or slotted lugs, for receiving the bent lever or bellslot in the shaft I, and at its back end there is a spiral A spring, q, which bears against the end of the rod with a constant pressure.

The pin through the rod passes through the shaft on each side, and enters a loose collar, lr.

S' is a staple, which is fast in the frame, as s een at t t.. This acts as a stop to the downward movement of the collar r and rod o. v The inner ends of the bent levers H enter the groove in the collar p, on the end of the rod o, so that when, by a longitudinal movement of the shaft I, the

' collar r and rod o are stopped bythe staple s,'the n.

gers of the bent levers H are thrown forward to the centre, by the continued movement of the shaft.

The longitudinal movement of the shaft ceases when theingers uimily grasp-the can.

At the time the can is thus grasped, the gear-wheel V, on the shaft I, is carried down and engages with the gear-wheel W, on the horizontal shaft X.

This shaft X is in constant motion, by means .of la belt on the pulley y, or it may be revolved by hand, by means of a crank.

The can is held in the position seen in thel drawing, sufficiently long to give the corner one or more revolutions in the melted solder contained in the reservoir B. A sufficient quantity (jl-solder isplaced in .the can, which is melted bythefcontact ofthe can with the soldering-iron C.

The elasticity given the iron by means of the rod Dallows it to keep in close withl the can, notwithstanding any ineqnalities of surfacewhieh may coeur.

The solder taken up by the corner of the can from the reservoir, and the solder which is Amelted inside the can, meet and form a perfectly tight joint.

' When the can has been given a full revolution (or more) in this position, the pressure is removed from the treadle J, when the shaft I is thrown back to its normal 'conditionby the spiral spring I, and is ready for another operation. As represented in the drawing, the can is in position, but the shaft has not yet received its longitudinal movement-by pressing upon the treadle'.

a is a cavity'for collecting any loose solder which may dropfrom the can during the process, which solder is ladled back into thereservoir.

At'the front edge of the reservoir thereisa copper or other metallic block, for the end of' the can to strike and rotate against, which block transmits the heat to theoan, there materially assisting in fusing or melting the solder on and outside, which block e, as seen at e', (fig. 2,) receives the end 0f the can, the shoulders of which recess or block also serve to wipe the surplus solder from the joint.

c is the door, for introducing fuel into the stove.

D'. is the smoke-pipe or ue.

With this machine the services of skilled workmen are not required for soldering. The operation may be performed by boys in -the most perfect manner, and with great rapidity.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

1. In combination with the heating-stove A and the reservoir B, the pivoted soldering-iron C and rod D, all arranged and operating substantially as described.

2. The bent levers H, grooved collar p, orits equivalent, the collar m1, the rod o, and the collar Lfr, combined arranged, and operating substantially' as described. i

3. In combination with the mechanism described, for holding and revolving the can or other article to be soldered, the soldering-iron C, whereby solder is melted on the inside of the can, substantially as described. l
